Floor joint sealing in Dartmouth Park
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk generally cracks where there’s movement, so we use a flexible sealant that moves with the floor. We work on thresholds, tiled floors and wet room & bathroom floors, and people most often call us about gaps opening between the floor and skirting and open joints around bathroom floor edges.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
Big or small, it’s backed by our 12-month guarantee.

Different surfaces, different methods
Wet room and bathroom floors
Floor joints in bathrooms take water every day. We seal them with anti-fungal sanitary silicone to keep water out of the edges.
Concrete floor joints
Open concrete joints chip at the edges when wheels cross them. Sealing them supports the edges and keeps dirt out.
New homes and floors in Dartmouth Park
Many of London’s new homes are flats in bigger developments, where snagging may go through the developer or managing agent. Floors around Greater London run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
For site and facilities teams at buildings such as Acland Burghley School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. If you look after a church, hall or community building such as Church of St Mary Brookfield, floor and skirting joints in halls and kitchens wear like any others.

How we quote for floor joint sealing
The quote reflects the job in front of us. We take into account:
- The old material and how stubborn it is
- The amount of work
- Any mould that needs treating
- Whether the work is at height
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Helping us quote
To help us quote quickly, let us know:
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- Where the job is, and your postcode
- Whether it’s a home or a business
Getting a quote is simple: tell us what needs doing and where and its rough size. Photos by email help us understand the job.
What happens if it’s left?
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why us?

What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Bouncy or failing floorboards
- Water getting under the tiles from elsewhere
- Concrete repairs beyond the joint
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
What we seal
- Wet room & bathroom floors
- Skirting boards
- Concrete floor joints
- Tiled floors
- Thresholds
- Commercial floors
What we do, step by step
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most rooms, longer for large commercial floors for a typical job. In a London area like Dartmouth Park, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We look at the gap and the floor type and agree the right sealant.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Preparing for the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Clear the area around the work

Your questions about floor joint sealing in Dartmouth Park
Do you cover Dartmouth Park for floor joint sealing?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before work begins.
Is caulk good enough for skirting?
Caulk can’t cope with movement or water. Floor edges move through the year, so a flexible sealant suits them better.
Can you seal where the floor meets the bath panel?
Yes. Where a floor meets a bath panel, kitchen plinth or skirting in a wet area, we use a flexible silicone so water can’t get into the gap.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
